Use a cotton swab for this. Immerse the treated parts in a bath of water-displacing oil. This will protect the finish from rust, sweat, and body oil. Leave the parts in the oil bath for 45 to 60 minutes, until they have cooled. Part 4. Polish the parts to be blued. Again, steel wool or to grit sandpaper will work to remove any loose rust, scarring, or pitting from the gun metal.
Clean away any dirt, oil, or grease that remains chemically. Coat the gun metal parts with the rust bluing solution. The rust bluing solution is typically a mixture of hydrochloric and nitric acid.
This solution actually encourages the metal to rust, but to do so in a uniform manner. Instead of coating the parts with the acid solution, you can instead place an opened container of the acid solution with the gun parts in a cabinet and seal it for a period of 12 hours. The acid evaporates from its container and condenses around the gun metal. This method is called fume bluing.
Another variation is to coat the gun metal parts with the rust bluing solution and then put them into a fume cabinet or, in this case, a damp cabinet for the same 12 hours. Often, a first layer is applied as a primer before coating the parts a second time and then placing them in the damp cabinet. Immerse the gun metal parts in boiling distilled water. This stops the rusting process by removing the acid solution. Scrub away the red oxide rust that has formed, leaving the black oxide finish underneath.
The surface rust is normally removed with a carding brush or wheel, which features very soft and thin wire bristles. Repeat the acid treatment, boiling, and scrubbing until you have achieved the desired level of bluing.
In some cases, the metal may develop as deep a coloring as it can, making further bluing attempts counterproductive. Coat the gun parts with oil. The oil inhibits the formation of rust and protects the metal finish from dirt, sweat, body oil, and wear. Include your email address to get a message when this question is answered. Submit a Tip All tip submissions are carefully reviewed before being published. Before using any of the bluing processes described above, make sure the gun is unloaded!
Also remove the gun handle or stock. Helpful 1 Not Helpful 2. With all bluing processes, work in a well-ventilated area. The caustic salts used for hot bluing are especially noxious. Helpful 1 Not Helpful 0. Do not attempt the hot bluing process on aluminum. It will trigger a violent reaction with the caustic salts bath, which may lead to severe chemical burns.

Oils will block uniform penetration so they must be removed completely.
Degrease using the methods and materials you believe will work best for the steel you are bluing. Acetone, denatured alcohol, and brake parts cleaner are effective chemicals for removing both synthetic and natural oils. You can find this degreaser at: www. The bluing process is often accelerated and intesified with the use of heat. On a molecular level, heat gets things moving! All things become more pliable and receptive to change when they are heated.
This science can be applied to bluing steel as well. Warm steel will take bluing faster and often deeper than cold steel. It's important to note that extreme heat is not necessary, and should not be used unless by a trained metal artisan or blacksmith. Heating steel with a hair dryer or heat gun is sufficient to get all the desired benefits. Heated steel should not be so hot that in can't be handled.
If using a heat gun be mindful of non-metallic parts that could be damaged by heat such as wood, plastics and resins.
Never heat Van's Gun Blue. Heating the bluing itself could create vapor that may be harmful to breathe. Only heat the steel being blued. Other proposals bring out stark partisan rifts. Gun ownership is closely linked with views on gun policies. This is true even among gun owners and non-owners within the same political party, according to the April Center survey. Among Republicans, gun owners are generally less likely than non-owners to favor policies that restrict access to guns.
Democratic non-gun owners are generally the most likely to favor restrictions. There are similar-sized gaps among Republicans who own guns and those who do not on banning assault-style weapons and high-capacity magazines. Among Democrats, there are modest gaps on gun policies by gun ownership. For instance, while majorities of Democratic gun owners and non-owners both favor banning assault-style weapons and banning high-capacity magazines, Democratic gun owners are about 20 percentage points less likely to say this.
Americans in rural areas typically favor more expansive gun access, while Americans in urban places prefer more restrictive policies, according to the April survey. Even though rural areas tend to be more Republican and urban communities more Democratic , this pattern holds true even within each political party. Democrats favor more gun restrictions regardless of where they live , but there are still some differences by community type.
